One popular type is the spray or fogger. These penetrate the cracks and crevices inside the house where insects nest. Users will need to leave the house for a period of time while the chemical works.

When using foggers, read the warning labels regarding use around open flames. The pilot lights on gas furnaces and appliances will ignite the insecticide if it reaches a high enough concentration in the home.

Pest repellents keep insects and rodents from entering the home. Common examples are sprays that repel dogs and wild animals from gardens and flowerbeds, or spray-on mosquito repellents that can be used on skin or clothing.

Pest traps will kill or confine rodents or insects. Common examples are the mousetrap and the roach trap. Traps incorporate some type of bait.

Poisons are ingested directly into the pest. Keep in mind they can also be harmful to household pets or small children.

Be sure to read the pesticide package carefully and follow all instructions.
